1- make her suck on your fingers afterward... you'll still smell like her but it's just a hot thing to do in the moment.
with my man... i don't always get a chance to 'fully' get the smell off me but that's deliberate
i sometimes sneak a smell while sitting at my desk at work when i get a free moment. it just takes me back to thirty minutes prior and then my day is just that much better. smelling of your SO i think is the best way to start your day!
